EGG-HEATER.

Speccation of Letters Patent.

Patented Sept. 5, 1905.

Application filed December 21,1904. Serial 110.237,75.

Be it known that IVALLAen R. .Mani r-r,a citi- Zen of the United States,residing at Brighton, in the county of Suffolk and State ofMassachusetts, have invented new and useful 1mpr'overnents inEgg-Beaters, of which the following' is a specification.

'lhis invention relates to an improved egg'- beater', the object of theinvention being' to pr'ovide a cheap and simple device, easilymanipulated and dur'able in its construction, which by the exercise of aslight arrrount of labor' will irrrpart a r'apid oscillating' rotaryrrrotion to an agitator' which is shaped in such a manner as tothoroughlyY stir and beat eggs, whip cream, and the like.

'lhe object of the invention is, fur'tlrer', to pr'ovide a device soconstructed that by r'otation of the agitator air will be forced throughthe liquid, so as to ver'y much lessen the time necessary to thoroughlybeat the eggs, whip the cream, or the like.

The invention consists in the combination and arrangement of parts setfor'tlr in the following' xspecification and particularly pointed outlin the claims tlrer'eof.

lteferrirrg' to the drawings, Figure 1 isa plan view, partly in section,on line 1 1 of Fig. Z of rrry improved egg-beater'. Fig. Qis a section,partly in elevation, taken on line 2 2 of Fig'. 1. Fig'. 3 is a planview, partly in section, similar to Fig'. 1, illustrating a modifiedfor'rrr of agitator'. Fig'. 1 is a section, partly in elevation, takenon line t at of Fig. 3.

Like nurrrerals refer' to like parts throughout the several views of thedrawings.

.lnthe dr'awings, 5 is an agitator' for'rned ofa plur'alityof curvedsheet-metal arms 6 6, said arms pr'efer'ably radiating' fr'orrr a commoncenter' T and having spaces 8 S ther'ebetween. The outer' ends of thearms T ar'e joined together' for the purpose of giving strength to thestructure by a wire E). Each of the armsti is provided with a port 10,said ports being' formed by str'iking up a flange 11 fr'orrr thematerial of which said arms are constructed. '.lo each of the arms (S 1sattached a tubular aerator 12, by rrreans of which during' the r'otheegg-beater when said egg-beater' is placed in a vertical position andconstitutes a pivot about which the agitator' rotates.

The agitator' 5 is Vfastened to a cylindrical shank 1?), and mountedupon said cylindrical shank is a tubular slide 1st, rrrovablelongitudinally upon said shank, said shank rotatable within said slide.The nredian lines of the tubular aerators 12 preferably lie in a planeat rig'lrt angles to the median axial line of the shank 13. A pin 15,fast to said slide 11, projects inwardly therefrom into a helical groove16, for'rrred upon the periphery of the shank 13. A handle 1T is fast tothe upper end of the tube 11, and a spiral spring 18 is located in theupper' end of said tube, the upper end of said spr'ing bear'ing againstsaid handle, the lower end thereof bearing against the upper end of theshank 13.

The general oper'atiorr of my improved eggheafer is as follows: 'l`heagitator 5 is placed in the liquid to be whipped, said liquidpr'efer'ably contained in a bowl or other appropriate vessel and ofadepth sufficient so that said agitator' will be entirely submergedtherein. The pivotal center' T of the agitator rests upon the bottom ofthe bowl, and the device is held with the shank 13 and slide 11 in avertical position, as illustrated in Fig. 2. Ylhe oper'- at`or pressesdownwardly upon the handle 1T, conrpr'essir'rg the springl 1S andpushing' the slide ltdownwardly against the action of said spring 18.'lhe slide 11- and handle 1T ar'e held against rotation by theoper'ator', so that as the pin 15 is carried downwardly by said slide 1tthe shank 13 is rotated by said pin in connection with the helicalgroove 1G, formed in said shank 13, and as said shank rotates theagitator' 5 as a whole, Yfast thereto, rotates therewith in onedirection, and when pressure is released upon the handle 1T the spr'ing1S, reacting, raises the slide l1 andA rotates the shank 13, togetherwith the agitator 5, by means of the pin 15 and groove 11' in theopposite direction. 'lhus it will be seen that the agitator' is rotatedalternately in opposite directions by pressing downwardly upon andreleasing the handle 1T. 'lhe curved arms (S f5 passing' through theliquid act to heat or whip the same, and this action is still furtherassisted by the flanges 1l, which come in contact with the liquid andguide the same through the por'ts 10, formed in said ar'rrrs 6. lnaddition to the dripping and beating' action of TOO the arms 6 and theflanges 11 the aerators 12 l form a very important and substantial partin the whipping and beating' of the liquid, for said aerators being'lillcd with air as they pass through the liquid force this air throughthe liquid under pressure and very much accelerate the whipping' orbeating ofthe liquid for the purpose of changing said liquid to a frothyconsistency, such as whipped cream, eggs for frosting, and the like.

In Fig'. 3 a modified form of my invention is illustrated in which thearms 6 6 of the agitator 5 are formed from strips of sheet metal having'substantially parallel sides. Said strips of metal are fast at a commoncentral point to a shank 13, which is rotated by a slide 14, connectedthereto by a pin 15, similar to the form illustrated in Figs. 1 and 2 ofthe drawings, except that in the modified form the slide la instead ofbeing a tube is made of a solid cylindrical rod with the handle 17integral therewith, and this rod may be made of wood to cheapen theconstruction, the pin 15 being' fastened to the rod and projecting intothe helical groove 16, formed in the shank 13. The spring' 18' in themodified form is inclosed in the tube 13', the bottom of said springbearing against the arms 6' at the point where they intersect in thecommon center 7 and the upper end of said spring' bearing ag'ainstthelower end of the slide 14', the action of the device as a whole in themodified form being sustantially the same as that illustrated in Figs. 1and 2. The difference in construction is principally useful in thatwaste strips of metal may be used, thus very much reducing the cost ofthe device as compared with arms of the shape illustrated in Fig'. 1 ofthe drawings, and, further, the slide 111, as hereinbefore stated, beingmade of a4 solid cylindrical rod may be formed of wood, if so desired.It is further noted that while in the form illustrated in Figs. 1 and 2the aerators 12 are each supported upon its respective arm in the formillustrated in Figs. 3 and L1 the aerators 12 extend from one arm 6 tothe arm adjacent thereto.

Having thus described my invention, what I claim, and desire by LettersPatent to secure, is-

1. As an article of manufacture, an eggbeater comprising in itsconstruction a shank, an agitator fast to said shank, and an aeratorconsisting of a hollow tube fast to said agitator, the median line ofsaid aerator lying in a plane substantially at right ang'les to themedian line of said shank.
